[Brian Lavender]

I have some code that has the following snippet, but it has this
u_int32. What the heck is u_int32?

"There are two ways of constructing a software design. One way is to
make it so simple that there are obviously no deficiencies. And the other
way is to make it so complicated that there are no obvious deficiencies."
